The like. Of concrete formwork, with a penetrated by the insert body and in the installed state transversely to Disk-shaped locking body extending along the longitudinal axis of the associated insert body.

For various reasons it is necessary to use certain parts within a formwork Construction of a concrete structure can be ordered to leave in the finished concrete. In numerous cases it is It is then important to prevent a medium, namely water, from making its way from one side of the finished concrete structure along the outside of such a body remaining in the concrete, here in general referred to as insert body, this applies to, for example, to the other side of the concrete structure Foundations, pool walls, etc.

In a known locking device (DE-GM 19 16 515) is made of a wire or a rod existing spacer provided with a square plate, which is fixed by welding. It This is a finished unit in which the position of the plate is specified. Furthermore comes the known locking device only for those cases in which the spacer consists of a weldable material consists or of a material that is not adversely changed by welding.

The invention is based on the object of providing a locking device of the type mentioned at the beginning create, which are located at the desired location of the Can attach the insert body concerned without damaging its surface or the structure of the material to influence the insert body unfavorable.

To solve this problem, the invention provides that the disk-shaped locking body consists of two viewed with interconnected parts, namely a relatively rigid outer tube and a sleeve-shaped, relatively soft inner part, the outer part surrounding the inner part radially, and that the Inner part has a tight seat for the tubular or rod-shaped insert body forming passage.
